Since 3b is a factor of 9b, it is automatically the GCF.

How does factorising work?

Here is an example of factorising:3ab+9bThe answer would be: 3b(a+3)First, in 3ab+9b, you have to find LIKE TERMS. Like Terms are numbers, letters, etc. that are present in both the 'sides' (3ab is one side, 9b is the other). b is present in both. Now, you may be wondering about the 3 in the answer - this one: 3b(a+3). This 3 is here because it is the highest common factor for both 3 and 9 in (3ab+9b). In other words, three goes into both 9 and 3.9 divided by 3 = 3 (this part - 3b(a+3) )3 divided by 3 = 1 (this part - 3b(a+3) )You don't need to put 1a, just a, because they are the same.I hope you understood this. If not, get your teacher or a friend to explain it :)Meanwhile, test yourself with these:4ab+3a7b+28ab6ab2 + 7a2 b (this one's harder!)

The sum of two numbers is 14 six times the first number minus three times the second number is 3 Find the numbers?

a + b = 14, so a = 14 - b; 6a - 3b = 3;substitute: 6(14 - b) - 3b = 3, ie 84 - 6b - 3b = 3, ie 81 = 9b so b = 9 and a = 5
